The RF Meter Click Board™ comes designed to let the user measure as well as keep a check on the radio frequency levels. This radio frequency power measurement device contains a 12-bit MCP3201 ADC and AD8318 demodulating logarithmic detector. It covers a wide radio frequency range, which varies from 1 MHz to 8 GHz, with an accuracy of 1.0 dB over 60 dB range (approximately) below 6 GHz. The board has been provided with an external antenna by way of which, it catches the signal. This signal is then forwarded to the AD8318 logarithmic amplifier for processing. The voltage produced here gets fed to the fed into an MCP3201 ADC so that RF levels can be precisely determined. The antenna connector, which is being provided to the RF Meter Click Board™, is a standard SMA type and it is compatible with the GSM antennas.
Since the AD8318 has a much wider frequency response; the user can put this board to use in a huge variety of applications by choosing the compatible antenna option.
AD8318 Demodulating Logarithmic Amplifier/ Controller
The AD8318 is a demodulating logarithmic detector. This amplifier processes an RF input signal for precisely converting it into an equivalent decibel-scaled output voltage. The AD8318 features a high level of logarithmic intercept stability at various temperature conditions and has a 10 Nano second response time. It has an in-built temperature sensor whose output is available through the TEMP OUT pin.
Board Connection
The RF Meter Click Board™ communicates with the target board MCU by making use of the mikroBUS SPI interface (CS, SCK, MISO pins), with additional TEMP OUT pin.
SMD jumper
The RF Meter Click Board™ comes equipped with an SMD jumper (zero Ω resistor) for setting the logic level either at 3.3V or at 5V.
Applications
The RF Meter Click Board™ proves highly useful in monitoring and measuring radio frequency levels. Since it ensures proper functioning of the applications and leak detection too, this board usually gets employed in testing equipment that includes RF transmitters or relays, in PA set point control and level monitoring, RSSI measurement in base stations, WLAN, WiMAX, and radars as well.
